(Cl. 10S-13) 3 Claims. 1

This invention relates to roong and siding structures.

More particularly, this invention relates to metal strips or sheathing for sheathing and weather stripping sections of roong and the like.

It is an object of the present invention to provide an improved form of metal-sheathed and weather-stripped roong, siding or the like.

It is a further object of the invention to provide metal sheathing and weather stripping for roongs, sidings, and the like, which are simple to fabricate and to assemble on a construction job.

These and other objects of the invention will be apparent from the ensuing description and the appended claims.

One form which the invention may assume is exemplified in the following description and llustrated by way of example in the accompanying drawings, in which:

Fig. 1 is a fragmentary, perspective view of a roof provided with roofing sections, and sheathed and weather stripped in accordance with the invention.

Fig. 2 is a fragmentary section taken along the slope of a roof and showing, in exploded view and on a larger scale than in Fig. 1, the manner in which the parts are assembled.

Fig. 3 is a view similar to that of Fig. 2 but` showing the parts assembled.

Fig. 4 is a section taken along the line 4 4 of Fig. 1 showing the manner in which abutting ends of roofing sections and sheathing strips are sealed or weather stripped.

Fig. 5 is a perspective view of a hipped roof showing the manner in which the inclined ridge thereof may be weather stripped in accordance with the invention.

Referring now to the drawings, roofing strips IV are provided, such strips being of lumber, plywood, composition board or whatever other material desired, and such strips are laid in overlapping relationship, in the usual manner, on rafters 2. Each such roofing section is provided with a metal sheathing 3, which is most advantageously made of aluminium or an alloy of aluminum but which may be made of any other metal or flexible weather-resistant material which can be fabricated into the desired form. The lower or leading end of each such strip of sheathing is bent at Il to provide a U-bend, the lower leg 5 of which is spaced somewhat from the bottom portion of the roofing section to provide a recess E. The rear or trailing end of each 2. sheathing strip 3 is ilush with the rear end Ill of the roong section.

Lower and uppersealing strips I I and I2 are also provided, as shown more clearly in Figs. 2 and 3, such sealing strips being preferably of the same material as the sheathing strips 3. The lower sealing strip II is bent at I3 to provide a rightangle bend, thus providing a stepped contour or Z-section having a lower step I4 and an upper step I5. The upper sealing strip I2 is similarly formed, being bent at right angles at I6 to provide lower and upper steps Il and I8, respectively. As shown. the sealing strips II and I2 are preferably of relatively heavy gauge metal and the main sheathing 3 is of relatively light gauge.

The parts thus described may be `completely assembled on the job, or they may be provided in semi-assembled or prefabricated condition. In either case, each roong section I is iitted with a sheathing strip 3. To the rear edge of each sheathed section is nailed a sealing strip II, as shown. A sealing strip I 2 is inserted in the recess 6 at the forward edge of the sheathed section and is similarly nailed to the section I. The thus assembled units, which, as stated, may be prefabricated, are laid on the rafters and nailed thereto by nails I9 in the usual manner. Each higher unit is interlocked with the next lower unit by engagement of the lower step II of its lower sealing strip with the recess ZIJ olf the next lower unit.

If desired, each sheathing strip 3 may run the entire length of a roof. Preferably, however, each such strip runs only the length of a single roofing strip, and at the joints between adjacent roofing strips there is provided a sealing structure is illustrated in Figs. 1 and 4. Referring to these figures, and more particularly to Fig. 4, adjacent ends of sheathing strips 3 are bent downwardly and upwardly to provide U-bends 25, and a sealing strip 2'6 of inverted U-shape and of heavier gauge is provided, being formed of the same material as the sheathing strip 3. The sealing strip 26 is inserted with its legs received between the legs of abutting U-bends.

Similar provision may be made for weather stripping or sealing the horizontal ridge 2l of a roof (see Fig. 5) and, as there shown, to weather strip the inclined ridges 2B, separate corner pieces 29 may be provided. Each of the corner pieces 29 will, of course, be provided with a metal sheathing 3a, and the joints 3l) formed with the adjacent roofing strips will be Weather stripped exactly as described above with reference to Fig. l4. Similar, but concave pieces may be used to Weather strip the valleys of a roof (not shown).

The advantages of the design and structures `thus illustrated are manifold. Thus, all of the :metal parts are easily fabricated by conventional :operations such as cutting, bending and stamping. The sheathing strip 3, the upper and lower .fsealingstrips Il and I2 and the U-strips 26 are easily assembled on the job, or provided in prefabricated or semi-assembled condition. Very little labor and no special skill are required in providing a roong sheathed and Weather ystripped in accordance with the invention. The :structure may be even further simplified by eliminating the upper sealing strip I2, employing only the strip H and engaging its upper step I5 in the recess 6 of the next higher unit.

The design of the invention is particularly advantageous in the case of a low pitch roof. Such roofs have advantages among which are lower cost of construction and pleasing appearance, but because of drainage and for other reasons higher pitch roofs have been preferred in the field of residential construction. The design of the present invention provides an effective form of sheathing, `weather stripping and water-proofing which renders low pitch roofs more practicable without, at the same time, increasing cost substantially.

While I have illustrated and described my invention in detail, it is to be understood that various changes may be made therein by those skilled in the art without departing from the spirit of the invention as dened in the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A structural unit for roofs and the like, comprising a body portion, a sheathing therefor of light gauge metal overlying one surface of said body portion and extending over and under an edge thereof to provide a recess therebeneath, a irst metal sealing strip of heavy gauge and of stepped cross section, one step thereof loeingA received within said recess, and a second, complemental metal sealing strip of heavy gauge disposed at the opposite edge and on the opposite side of said body portion, said second strip being adapted to interlock with the first strip of an overlapping unit both said sealing strips eX- tending the length of said body portion.

2. An assembly of structural elements comrising a metal sheathing strip having a leading edge Which is formed into a U-bend to provide a downwardly extending portion and a rearwardly extending portion dening a marginal recess, and a pair of similar sealing strips each extending the length of said leading edge and bent medially vand longitudinally to provide flat sections on opposite sides of the medial bend, said sealing strips being disposed in interlocking, sealing relationship with the flat section of one such strip in said marginal recess adjacent said rearwardly extending portion, one fiat section of the other sealing strip in a position to be nailed to an underlying structure, and the other at sections in adjoining, interlocking relation.

3. A roofing structure or the like, comprising a plurality of overlapping sections providing overlapping joints each formed by the overlap of the leading edge of one such section and the ltrailing edge of an adjacent section; said structure also comprising sheathing means in the form of a metal sheathing for each section which extends over and under the leading edge thereof to provide a recess therebeneath; said structure also comprising sealing means for each said joint in the form of a pair of similar metal strips each extending the length of the joint and being bent medially and longitudinally to provide flat sections on opposite sides of the medialV bend; said metal strips for each joint being so disposed that one flat section of one strip is disposed within said recess, one at section of the other strip is fixed to the Ytrailing edge of the joint and the other flat sections are in adjacent, interlocking relation.
